4 buff polish hens needed/MN

Greetings: I'm looking for 4 buff polish hens my two boys can lease for the Dakota County Fair, August 8 - 11 Farmington, Minnesota. Their hatch date needs to be end of February or begining of March 2011. It's a long shot but I think I have to try. I'm willing to drive to pick up your birds. Thanks. JEN
